      What a coincidence. I used to teach a Spelling for Amateurs class, and most people couldn't even spell the name of the class.

        "Armature: A protective covering, structure, or organ of an animal or a plant, such as teeth, claws, thorns, or the shell of a turtle.

        However, when they graduated, they could draw claws like a pro.

    • I thought the same thing. But what about someone who's building/creating something new, especially someone without knowledge of lots of existings part types in database x, each time they do drawing for each little part in their design, run it through the search engine to see if it's something that's already been fabricated. Probably not the intended use though.
    • So you used to teach an art class where the people couldn't draw...hmmmm...

      1. It was a CLASS you TEACH...therefore you are there to TEACH them to draw.

      or

      2. After the class that you taught they still couldn't draw...who's fault is that really? There's or yours?

      Also, how is this modded as interesting?
    • the user's ability to sketch.

      Do designers/engineers/draftsmen actually learn to draw these days, or is it all CAD-based?
      • At Purdue there's not much drawing, but there is some. The main purpose of it is to show you how much more precise and accurate the computer generated versions are. So, you don't spend much time on it really.
        • Isn't Purdue where George Goble [purdue.edu] teaches? I wonder why his LOX BBQ lighting page was taken down.

          Anyway, back on topic, there's no question that CAD is more precise but during early design stages, precision is not the goal and too much focus on computer-generated perfection hinders the process. People tend to get wrapped-up in the workings of the software and can produce brilliant-looking, but comepletely stupid drawings and unworkable designs.

          My opinion is that CAD people should learn how to draw by hand
          • Isn't Purdue where George Goble teaches? I wonder why his LOX BBQ lighting page was taken down.

            Yes, it is. Also, you can find a site containing photos as well as audio clips from his infamous technique for lighting a charcoal grill here [doeblitz.net].

      I'll take the sinister uses with the good on this one. This is really exciting for engineers and tinkerers alike, because it means less time reinventing the proverbial wheel.

      Let's say I need gizmoX but it's not manufactured anymore. Fuck! No knock-offs, either. The local CNC shop says they can make it for me but they need a model. 3D modeling could take a while unless you have something similar to start with.

      So instead of PORING over an industrial parts catalog and missing the one close-enough part you needed but didn't expect to find under "444_T91_fillets" or whatever, you just search for matches using dimensions, materials, etc. Just a few minor tweaks to the mesh, export, send to the shop, and you just saved a lot of time.

      That said - the design and manufacturing industries have been writing ad hoc programs for searching for parts and tooling since the proliferation of computers, but it's nice to see that a general-purpose algorithm that could be more or less universally applicable is evolving from the efforts thus far.

      • "Hey Ben, I need that little thingie. You know, the one with the two parts and the stuff around it?"

        I don't think you need to go so far as editing to find a good use for this.

      Male your flavour? Try 8=====) (or 8==========) if you're looking for a more "exciting" experience).

      Pattern match, and boom! Instant porn results.

      And no, I cannot believe that I actually posted some ascii pr0n on Slashdot :) Just imagine what the poor search engine would have to do to match that horrible goatse ascii *shudder*. Maybe it'd return some astronomy websites dealing with singularities.

    I've been curious if there has been a hyperelegant neural network solution that can do everything from recognize handwriting to faces. Completely different applications would only require retraining. So you wouldn't hear about specific applications like this, but one breakthrough that can simply, elegantly be applied anytime recognition must be performed. Are there any real (not patent or such) related reasons this doesn't exist?

      I've been curious if there has been a hyperelegant neural network solution that can do everything from recognize handwriting to faces. [...] Are there any real (not patent or such) related reasons this doesn't exist?

      Aside from the fact that about a third of the brain (if I remember correctly) is dedicated to visual processing and that the brain has a hundred billion neurons, each neuron firing at up to 1KHz and with thousands of connections to other neurons? :)

      It's an enourmously complex task to be able to do this reliably. Recognizing a straight-on photograph and matching it up with a corresponding mugshot is a whole lot different than seeing the side of a person's half-shadowed face from slightly behind them and recognizing that as the same Alice who held up the convenience store on Tuesday.

      Handwriting recognition is orders of magnitude easier to do, since it's a lot easier to recognize similarities between a sample of writing and previously analyzed samples. In fact, there's a lot of research into this [ibm.com] already. Facial recognition is slowly getting there, but people are still stumbling over the same mistakes that were made decades ago -- attempting to formalize facial recognition by defining a set of rules and matching to those rules. Much like spam filtering, this works to a degree until the differences between the one you want and the one you don't no longer fits within the rules.

      Neural net + genetic algorithms/programming to refine the net's connections and behavior is probably a good approach. Finding a means of populating, storing, and computing hundreds of billions of nodes in the network is the real challenge I think. Of course, take everything I've said with a huge grain of salt as this is a subject I'm fascinated by but have little practical experience with.
